Consider the following scenario.
I have a function that accepts paired name/value arguments, e.g.
Given a list of complex numbers z, return a list zSorted such that the numbers that are farthest from the origin (0+0i) appear f...
Output logical "true" if the input is the answer to life, the universe and everything. Otherwise, output logical "false".
Given a and b, return the sum a+b in c.

Given an input vector x, find all elements of x less than 0 or greater than 10 and replace them with NaN.
Given the number x, y must be the summation of all integers from 1 to 2^x.
For instance if x=2 then y must be 1+2+3+4=10.
Return 1 if the input is sorted from highest to lowest, 0 if not.
1:7 -> 0
[7 5 2] -> 1
Given the input n, return true if n is odd or false if n is even.
Try out this test problem first.
Given the variable x as your input, multiply it by two and put the result in y.
